Translation of the Original Operating Instructions Micro Milling Machine MF 70 Dear Customer, By purchasing your PROXXON Micro Milling Machine MF 70, you have chosen a good-quality, high-grade machine. The PROXXON MF 70 MICRO Milling Machine is equipped with the proven KT 70 microcoordinate table. This enables you to perform small, precise milling operations on metal, plastics or wood. In order to operate the milling machine and the accompanying accessories safely and cor- rectly, please read the enclosed safety information and oper- ating instructions prior to operation. WARNING! Read all safety warnings and instructions. Failure to follow all safety warnings and instructions listed below may result in electric shock, fire and/or serious injury. KEEP ALL SAFETY WARNINGS AND INSTRUCTIONS FOR THE FUTURE ! Risk of injury! Never work without dust protection mask and safety glasses. Some dusts have a haz- ardous effect! Materials containing asbestos may not be machined! Only in dry rooms Please do not dispose of this electrical machine in the household refuse! The noise level can exceed 85 dB(A) during work.

Spanners Description of the machine The PROXXON MF 70 MICRO Milling Machine is the ideal machine for all fine and precision milling work for metals (cast iron, steel, brass, aluminium), plastics or wood. With the high spindle speed of 5,000 to 20,000 rpm (enabling the use of the smallest milling cutter diameters) in conjunction with the high-precision KT 70 microcoordinate table, all pre-conditions for precise and clean operation are fulfilled. The basic equipment includes: – Milling spindle with Z-pillar and stable base – Collet chuck block with collet chucks – (Ø 1.0; 1.5; 2.0, 2.4; 3.0 and 3.2 mm) – KT 70 microcoordinate table, complete – Clamp set with fastening materials – Fastening screws for KT 70 micro coordinate table – Auxiliary tools – Operating instructions and safety regulations Technical data Voltage: 230 volts, 50/60 Hz Power rating: 100 watt Spindle speed 6,000 – 20,000 rpm Vertical adjustment travel 83 mm Lateral adjustment travel 134 mm Longitudinal adjustment travel 46 mm Table size 200 x 70mm Scale rings 1 turn = 1 mm 1 graduation line = 0.05 mm Dimensions of T-grooves 12 x 6 x 5 mm Spacing of T-grooves 25 mm Size of base 130 x 225 mm Overall height 340 mm Weight approx. 7 kg Noise emission ≤ 70 dB(A) Vibration 2.5 m/s2 General measuring uncertainty K=3 dB Noise/vibration information Please note that the sound and vibration measurements in particular have been performed with Proxxon bits and cut- ters. When using third-party brands we cannot guarantee compliance with the statements given here! The information on vibration and noise emission has been determined in compliance with the prescribed standardised and normative measuring methods and can be used to com- pare electrical devices and tools with each other. These values also allow a preliminary evaluation of the loads caused by vibration and noise emissions. Warning! Depending on the operating conditions while operating the device, the actually occurring emissions could differ from the values specified above! GB

Please bear in mind that the vibration and noise emission can deviate from the values given in these instructions, depending on the conditions of use of the tool. Poorly main- tained tools, inappropriate working methods, different work pieces, too high a feed or unsuitable work pieces or materials or unsuitable bits and cutters (here: saw blade) can signifi- cantly increase the vibration load and noise emission across the entire work period. To more accurately estimate the actual vibration and noise load, also take the times into consideration where the device is switched off, or is running but is not actually in use. This can clearly reduce the vibration and noise load across the entire work period. Warning: • Ensure regular and proper maintenance of your tool • Stop operation of the tool immediately if excessive vibra- tion occurs! • Unsuitable bits and cutters can cause excessive vibration and noises. Only use suitable bits and cutters! • Take breaks if necessary when working with the device! Assembly of the milling machine - Attach the compound-type table 1 (Fig. 2) to the base 2 with the 4 x M4 Allen screws supplied. - The milling machine must now be fastened to a stable work surface with 4 screws 3. Operation Installation of the collet chucks Important Disconnect the mains plug before changing tools. Tighten- ing the union nut without a suitable shank inserted, dam- ages the collet chuck. 1. Block the spindle with a spanner and release union nut 1 (Fig. 3). 2. Insert the required collet chuck 2 using suitable inserting tool 3. 3. Block milling spindle and re-tighten union nut. Note: All inserting tools must be tightened with as little protrusion as possible. Excessively protruding shanks vibrate and cause poor milling results. Setting the spindle speed The spindle speed can be adjusted continuously by means of the electronic control. In general: Large milling tool diameter = low speed Small milling tool diameter = high speed The correct spindle speeds are indicated on the table on the front of the milling machine. Milling Important Always wear protective goggles when milling. Always observe the enclosed safety regulations. 1. Fasten the work piece with the clamps supplied or in a vice. 2. Switch on milling machine at switch 1 (Fig. 4). 3. Adjust the required milling depth using handwheel 2. 1 turn = 1 mm feed 4. Tighten clamp screw 3. 5. Work with a suitable feed and with a suitable milling depth. The feed must always be against the cutting direc- tion of the milling tool (Fig. 5). 6. Release clamp screw 3 before readjusting the cutting depth (Fig. 4). Note: The MF 70 MICRO Milling Machine is designed for precise, fine machining. Therefore, adopt suitable milling depth and feed rate. Otherwise, poor quality milling results are to be expected. Furthermore, thermal damage may be caused to the electric motor due to continuous overloading. Adjustment of scale on compound-type table: The scale rings on the handwheels are moveable and can thus be set to zero without traversing the table. In addition to the scale rings, the KT 70 micro-compound-type table is equipped with a moveable scale for adjustment in the X direction 19 (Fig. 1). Adjustment of guide play Important Disconnect the mains plug before making any adjustments. All 3 axes of the milling machine are equipped with an adjustable dovetail guide. If, after a time, a guide is found to have too much or too little play, the play can be reset via the adjusting screws (Fig. 6). In order to adjust the play in the X direction, first release the nut 1 (Fig. 6). Then set the play using the set screws 2. Lock by re-tightening the nut 1. Adjustment of play for the other two axes is performed analogously. Note: Do not over-tighten the set screws as, otherwise, the guide may be damaged. Evenly tighten all the set screws. Maintenance, cleaning and care Attention: Disconnect the mains plug prior to every adjustment, mainte- nance measure or repair!

Note: Every device is dirtied by dust when working. Cleaning is therefore essential. To ensure a long service life, however, the machine should be cleaned with a soft cloth or brush after each use. Mild soap or other suitable cleaning agent may be used in this context. Solvents or cleaning agents containing alcohol (e.g. petrol, cleaning alcohols, etc.) should be avoided, since these can attack plastic casings. The apertures required for cooling the motor must always be kept free of dust and dirt.
